Last year Dietz sold 12 million cans of tuna compared to the 10 million sold during the previous year, an increase directly attributable to new customers brought in by the campaign. Profits from the additional sales, however, were substantially less than the cost of the advertising campaign. Clearly, therefore, the campaign did nothing to further Dietz's economic interests.
Which of the following, if true, most seriously weakens the argument? (A) Sales of canned tuna account for a relatively small percentage of Dietz Foods' profits. (8) Most of the people who bought Dietz's canned tuna for the first time as a result of the campaign were already loyal customers of other Dietz products. (C) A less expensive advertising campaign would have brought in significantly fewer new customers for Dietz's canned tuna than did the campaign Dietz Foods launched last year. (D) Dietz made money on sales of canned tuna last year. (E) In each of the past five years, there was a steep, industry-wide decline in sales of canned tuna.
C的意思是：更少的campaign的花销会带来更少的新顾客，比去年。与结论无关。作者: yammm 时间: 2018-7-24 23:02
【key】结论的具体化：whether the campaign led the profits less than the cost and did nothing to further D's economic profits.
